Research papers. American International Journal of Contemporary Research Vol. 3 No. 3; March 2013, - 162-176 p.In the process of T-72 tank modernization, reconstruction of the spherical pathway of the turret turning mechanism was carried out. Following the the turret load analysis at the moment of firing and identification of the allowance in the bearing, the turret turning mechanism was rebuilt completely. Analyses show that the cannon muzzle oscillation is caused by several factors. Having analyzed them, specific measures were adopted, such as for instance the elimination of allowance in the spherical pathway seating of the tank turret.Contents:
